Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adhesive tape cutting and applying device, and an object of the present invention is to provide an apparatus that can easily and efficiently cut and apply an adhesive tape to an object.

Generally, one method of fixing the deflection yoke and cathode ray tube of a color television is to use double-sided adhesive tape attached to a rubber wedge. Pasting adhesive tape one by one was accomplished by cutting the tape with a designated cutter, but this method made it difficult to position the tape, resulting in uneven tape application and cutting, and the tape sticking out. However, there are problems in that the appearance is not good, the tape is likely to be wasted when reapplying it, and the workers have to do simple labor.

In order to solve the above problems, conventional cutting and pasting devices have been used, but in this case, the object to which the tape has already been pasted is simply fixed at the time of cutting, and there is no space between the end surface of the object and the fixed blade. Because it is necessary to provide a space for the cutter to move, the cut tape will protrude from the edge of the object by the thickness of the cutter, and conversely, if the tape is pasted after being cut, the tape may During pasting, there is a moment when the tape becomes free in the air, making the pasting state unstable, and each has drawbacks such as poor appearance and waste of tape.

The present invention eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

FIG. 1 and FIG. 2 are a side view and a front view, respectively, showing the configuration before operation of one embodiment of the adhesive tape cutting and pasting device according to the present invention.

In the figure, 1 is a slide base, which can be slid freely in the directions of arrows A and B in the figure with a guide 2, and a guide plate 3 on the top surface.
is implanted and fixed, and is inserted through a pair of shafts 4 so as to be slidable upward (first direction) and downward (second direction) by their shaft portions 4a, respectively.

Each shaft 4 has a square base 4b at the upper end and a slide base 1
A stop ring 6 is urged upward by a spring 5 interposed therebetween, and is normally held in contact with the lower surface of the slide base 1.

Further, on the upper surface of the square base 4b of each shaft 4, a tape pasting plate portion 7a of a rubber wedge 7 (an object to be pasted) for fixing the deflection yoke and cathode ray tube of a color television is mounted.

In order to determine the mounting position of the wedge 7, the beginning of the slide base 1 is assumed to be further leftward than the position shown in FIG.

Reference numeral 8 denotes a fixed blade, which is implanted and fixed in the base 9, above which the adhesive tape 10 is led out in the direction of arrow C in FIG. It is positioned in contact with the

Reference numeral 11 denotes a sliding blade, which is provided so as to be slidable in the vertical direction so as to be able to cross-cut between the right end cutting edge in FIG. 1 and the left end cutting edge in the drawing of the fixed blade 8.

Next, the operation of the apparatus having the above configuration will be explained.

First, the slide base 1 slides in the direction of arrow B from the initial position of the head, and as shown in FIG. As shown, the tape 10 is led out in the direction of arrow C, and its leading end is brought into contact with the guide plate 3.

In this case, the tape application surface 7b on the upper surface of the application plate portion 7a is located above the upper end of the fixed blade 8, and is located below the tape 10 with a slight distance from it.

At this point, the sliding blade 11 starts to slide downward, and as shown in FIG. 3, it comes into contact with the tape 10 and bends and deforms it, and then presses and pastes it onto the pasting surface 7b of the pasting plate part 7a.

Subsequently, when the sliding blade 11 slides further downward, as shown in FIG.
0, and further push down the cutting tape 10a, the pasting plate part 7a, and the shaft 4 together.

Next, the lower end of the shaft portion 4a comes into contact with the base 12, and the downward movement of the plate portion 7a and the shaft 4 to be pasted is stopped, but the sliding blade 11 continues to apply a predetermined pressing force further downward, and the cutting tape 10a is stopped.
Then, the attachment plate portions 7a are pressed together with sufficient force.

Thus, the cutting tape 10a is attached to the attachment surface 7b of the attachment plate portion 7a.
It is firmly attached to the surface.

The sliding blade 11 then slides upward and returns to the position shown in FIG.
a and the sticking plate part 7a also slide upward and return to the position shown in FIG.

Next, after the slide base 1 slides back in the direction of arrow A, the above-mentioned pasted products 10a, ? a is removed and the sticking plate part 7a of the next wedge 7 is set.

Thereafter, in the same manner, the tape 10 is sequentially led out in the direction of arrow C for each step until it comes into contact with the guide plate 3, and is continuously cut and pasted.

According to the above procedure, the adhesive tape 10 is already affixed to the affixing plate part 7a with a predetermined pressing force before cutting, the affixing is cut in a stable state, and the cutting tape 10a is further affixed to the affixing plate part 7a with a certain pressing force. Since the three-step pasting procedure of pressing onto the portion 7a can be performed in one step, the number of man-hours can be reduced.

In addition, the tape 10 does not become free in the air during cutting, allowing stable cutting, and the sliding blade 11 moves integrally with the tape 10 and the application plate 7a, while cutting the tape between the fixed blade 8 and the tape 10. 10 cross cutting is performed, and the cutting surfaces of the sliding blade 11 and the fixed blade 8 can be set on the end face of the pasting plate part 7a, so the tape 10 is cut along the end face of the pasting plate part 7a and does not protrude, resulting in a clean appearance. There is no need to waste tape.

As described above, according to the adhesive tape cutting and pasting device of the present invention, the tip end surface has a predetermined dimensional width, and the fixed blade is fixed to the base so that cross cutting is possible between the fixed blade and the fixed blade. A sliding blade installed to be able to slide freely is moved forward, and the tip surface of the sliding blade presses the adhesive tape onto the surface to be applied, and then slides the adhesive tape, the object to be applied, and the shaft together. Then, the adhesive tape is cut by the shearing force acting mutually between the sliding blade and the fixed blade, and the tip of the sliding blade continues to move forward, and the cut adhesive tape is placed on the tape application surface of the object. Since the adhesive tape is applied by pressing and crimping, one downward movement of the sliding blade will cause the adhesive tape to be applied to the object with a predetermined pressing force before being cut by the tip of the sliding blade.
Since the three-step procedure of cutting in that state and finally crimping and pasting can be completed in one process, the number of man-hours can be reduced and manufacturing costs can be significantly reduced. The tape is strongly bonded by the pressure with the tip of the reciprocating sliding blade, and since the tape is already attached before cutting, there is no moment when the tape becomes free in the air (it is not possible to perform stable cutting, and the sliding blade The tape is cut along the edge of the object, and the tape is cut along the edge of the object while moving integrally with the tape and the object. The tape can be applied without protruding beyond the application surface, and the cut edge is clean, which improves the appearance and eliminates wasted tape due to reapplication.Furthermore, the shape of the sliding blade tip matches the shape of the tape application surface. For example, if the shape of the fixed blade corresponds to the shape of the tape application surface, cutting and application can be performed at the same time without any problem even if the tape application surface is irregularly shaped.
